Description

A Portable Anti-Turbulence Adjustable Deep Siphon Sampling Device

technical field

The utility model relates to the technical field of water quality monitoring, in particular to a portable anti-turbulence adjustable depth siphon sampling device.

Background technique

With the rapid development of social economy, the problem of environmental pollution in our country has become increasingly prominent, especially the water environment pollution has shown a trend of expansion and seriousness. In order to strengthen the monitoring of water environment governance and timely grasp and detect the distribution of pollutants in water bodies, a large number of water quality sampling and other work are required to ensure the timeliness and accuracy of the water quality of the water samples taken.

For the on-site water sampling work, in accordance with the "Surface Water Quality Standard" (GB3838-2002), "the water sample is required to settle naturally for 30 minutes after collection, and the upper non-sedimented part is taken for analysis according to the specified method". "Technical Specifications for Surface Water and Sewage Monitoring" (HJ/T 91—2002) stipulates that "if the water sample contains sedimentary solids, the collected water sample should be shaken well and then poured into a cylindrical glass container and left to stand for 30 minutes. Water samples that do not contain settled solids but contain suspended solids are transferred to the sample container and added to the preservative". The "National Surface Water Environmental Quality Monitoring Network Monitoring Task Operation Instructions" stipulates that "if the water samples at the monitoring section are clear, the site can be sub-packaged without natural settlement for 30 minutes." In actual sampling, however, it is difficult to implement the above specification. According to the requirements of the above standard, the water sample needs to be left in the sampler for 30 minutes, and then a straw needs to be inserted to a position 50 mm below the surface of the water sample to absorb the water sample one or more times. The operation is more troublesome. If the water sample contains a large amount of suspended matter, Water samples are drawn through the straw one or more times, which is easy to form turbulent water quality, resulting in a large amount of suspended solids in the taken water samples, which affects the detection of water quality.

In addition, with the update and development of technology, the current water quality collection technology has gradually developed into an automatic water intake method in order to be used in conjunction with water quality monitoring technology. Among them, there are various automatic water intake devices, including simple water intake devices such as water intake pipes and water bottles. , including a large water intake device connected to the water pump. The development of technology has provided great convenience for environmental quality monitoring and other fields, and improved the timeliness of detection. However, the problem of turbulent water quality is still a problem in the industry.

The adverse effects of water quality turbulence mainly include two aspects. First of all, the water samples contained a large amount of suspended solids, which affected water quality testing. Secondly, the accumulation of large particles of solid matter can also cause blockage of the water intake.

In order to overcome the adverse effects caused by turbulent water quality, after retrieval, many technical solutions have been disclosed in the prior art, such as Chinese Patent No. 200910024538.5, which discloses a method for protecting the water inlet of a water quality sampler , which intercepts a large amount of suspended matter and sediment through the primary protective filter and the secondary filter head, thereby protecting the water inlet of the collector. The device plays a certain role in preventing the blockage of the water inlet of the collector. However, the overall structure of this application is relatively complex and the cost is relatively high. In order to ensure the effective operation of the filter screen and filter head components, a cleaning device is inevitably added, which further increases the cost and structural complexity. China Patent No. 201210472785.3, the application discloses a water quality sampling device and a water quality monitoring system using the device, which passes gas into the airtight sampling device, relies on the gas to press out the water quality sample, and realizes water quality sampling, and the gas input part does not need In direct contact with water, it is not easy to cause clogging and damage, and because there is no additional suction power, there is no agitation during suction; however, although the gas parts of the application are not easy to clog, the process of obtaining water samples from the sample pool The mouth of the water pipe is open downward, and the process of automatic inflow of water samples may still introduce sedimentary solids and suspended particles, and long-term use will also lead to blockage of the water inlet. Moreover, the introduction of gas components increases additional costs, which is not conducive to popularization.

From the above analysis, it can be seen that most of the existing technologies overcome the defects caused by water turbulence from the perspective of protecting the water inlet. The common way is to increase the line of defense by adding filter screens or filter heads, but there is no such thing as water quality turbulence. Considering the source, therefore, it only treats the symptoms but not the root cause, and does not fundamentally solve the problem.

Chinese Patent No. 201420600029.9 discloses a new type of water quality collector. In this application, the collection bottle is placed in the water through the rod body, and the collection is performed when the water body is stable. The collection and closing of the sample, this device is not easy to stir during the collection process, and can avoid the inhalation of a large number of solid particles during sampling, overcoming the defects that the traditional collectors tend to make the water turbid and introduce a large amount of impurities. This application can be said to have thought of preventing the introduction of solid particles when taking water from the perspective of not generating water quality turbulence, but it still has the following defects: 1) the continuous sampling cannot be realized; 2) settings such as rubber bands or springs, etc. Parts, long-term shrinkage is easy to damage.

In order to make the collection of water samples continuous, there are also some water intake devices using simple principles in the prior art. For example, Chinese Patent No. 00122194.9 discloses a method and device for extracting liquid by siphon suction. This application case utilizes the law of atmospheric pressure and siphon phenomenon to achieve the effect of liquid extraction, making the water intake process continuous automation without using electric equipment. Chinese Patent No. 201010501514.7 discloses a vacuum pump-assisted siphon water intake device and method. The device is also based on the direction of saving energy, and uses the principle of siphon to start the siphon with a vacuum pump, so that the siphon water intake pipe can maintain continuous and stable operation. Though above-mentioned two kinds of devices have utilized siphon principle, try to adopt simple device and can finish automatic continuous water intake process. However, the scope of application is relatively narrow, and the defect of water quality turbulence that occurs when water is taken cannot be solved.

Therefore urgently need to develop a kind of simple and practical water intake device, can overcome the defective of water quality turbulent flow, can realize automatic continuous water intake process again.
